Berluto DRV 830-D steam pressure reducing valve, flanged, stainless steel
Piston-controlled pressure reducing valve for steam and hot water in stainless steel 1.4408 with PN 40 flanges DN 15 to DN 50, inlet up to 16 bar, outlet 0.3 to 2 bar, PTFE / EPDM / FEPM seals up to 200 °C.
The DRV 830-D is the flanged version of Berluto’s low-pressure steam reducer, DN 15 to DN 50 with PN 40 flanges. Piston control and a soft seat with PTFE and elastomer seals suit it to hot service: PTFE / EPDM for steam up to 150 °C, PTFE / EPDM / FEPM for steam up to 200 °C. Body and bonnet are stainless steel 1.4408 with 1.4404 inner parts, so hot water, condensate and aggressive liquids are covered too.
Inlet pressure is 16 bar and the outlet is set between 0.3 and 2 bar with a minimum pressure difference of 0.3 bar. Kvs values run from 3.0 to 12 m³/h. The inner assembly is a replaceable cartridge and gauge ports G 1/4” sit on both sides.
For outlet pressures between 2 and 10 bar see the DRV 832-D / 838-D; the threaded counterpart is the DRV 730-D.
Selection data we need
Medium (saturated steam, hot water), inlet pressure and temperature, required outlet pressure, steam or water flow rate, nominal size and flange standard, and whether the 200 °C seal set is needed.
Applications
- Low-pressure steam to heat exchangers, autoclaves and sterilisers
- Hot water and condensate systems
- Aggressive liquids at elevated temperature
- Flanged steam lines up to DN 50
